CUT-GRAIN CARRIER FOR HARVESTERS.

SPECIFICATION forming part of Letters Patent No. 643,037, dated February 6, 1900.

Application filed .Tune 26, 1899. Serial No. 721,818. (No model.)

To all whom t may concern:

Be it known that I, HENRY BRYAN, residing at Modesto, in the county of Stanislaus and State of California, have made certain new and useful Improvements in Cut-Grain Carriers for Harvesters, of which the following is a specification.

In reapers or harvesters, especially in the class known as headers,7 the endless draper or grain-carrying apron runs on a roller arranged directly behind the sickle-bar and at a right angle thereto. The lower end of such roller, which is the one adjacent to the sicklebar, being near the ground, sand, dust, and other loose matter are continually falling upon it, so that the friction of the bearing at that end is increased and effective lubrication prevented. I have overcome this difficulty by an improved construction. I have also providedV for adjustment of tension of the endless apron or carrier by an improved means, as hereinafter described.

In the accompanying drawings, Figure 1 is a horizontal section of the roller and connected parts. Fig. 2 is a plan View of a portion of the same. Fig. 3 is a transverse vertical sec-- tion on line 3 3 of Fig. 2. Fig. 4. is a plan view of the grain-carrier, part being broken As shown in Fig. 4, an endless traveling apron or grain-carrier a is arranged, as usual,

directly in rear of the sickle-bar y and runs over my improved roller l, which is arranged at the outer end of the sickle-bar and at a right angle thereto. As shown in Fig. 1, the body 1 of said roller is a hollow cylinder, and its circular heads or ends 2 2 are fitted closely thereinto and secured by screws. The said heads 2 2 have each an exterior shoulder or iiange 3, that abuts the end of the cylinder 1, and a wider interior liange 4., that iits into said cylinder, and a central circular interior projection 5, which constitutes the bearing oi' shaft 6. This bearing 5 forms practically the hub of the roller 1, which rotates freely on the shaft. It is apparent that by this construction and arrangement of the heads 2 2 dust, dirt, &c., are practically excluded from the bearings. Coincident oil-holes 7 are provided in one end of the body 1 of the roller and the head 2.

The roller may be moved bodily and laterally as required for adjusting the tension of the apron a to the desired degree. For this purpose the ends of the shaft 6 are screwed into the lateral sockets of sleeves 8, which are adjusted by screw-rods 9. The latter work in the ends of the hollow parallel bars.

10, constituting the side portions of the frame in which the grain-carrier a is arranged and adapted to work. The said rods 9 have circu mferential collars 1l, that work in contact with the `flat ends of the bars 10, and their threaded portions pass through and Work in the sleeves 8, which are correspondingly threaded internally.

A hand-wheel 12 on the outer ends of the rods 9 enables them to be rotated manually for taking up slack in the apron a. A longitudinal slot 13 is provided for the rollershaft 6 in the inner side of each bar 10 to allow adjustment of the roller, as stated.

By the above-described improvements the eiiiciency of this class of roller attachments for reapers, dto., is greatly increased.

What I claim is- 1. In a harvester, the combination with the endless apron, slotted side bars, transverse shaft, and means for adjusting the latter, of the rotatable roller for said apron, oomprising the hollow cylindrical body 1, circular heads having the central interior hub 5 and concentric interior flange 4: fitted within said body, and a shoulder 3 abutting the end of the latter, coincident oil-holes being provided in the body and one of the heads, substantially as shown and described.

2. In aharvester the combination with the apron, slotted side bars, and the apron-roller proper, of the non-rotary roller-shaft 6, having threaded ends, T-sleeves 8 having threaded lateral sockets for reception of the shaft ends, the screw-rods 9, working in the body of said sleeves, and provided exteriorly with fixed collars that abut the ends of said bars, and with hand-wheels for rotating them,`as and for the purpose specified.

HENRY BRYAN.
